The show won’t go on for Frank Ocean. The “Thinkin Bout You” singer has pulled out of his remaining European festival tour dates and his opening slot on Coldplay’s tour.

He expressed his regret over the decision in a statement released online (via MTV News).

“Let me start by saying I feel like an asshole right now, but a tough decision had to be made in regard to my schedule over the next months and the casualties of that decision include my appearances at upcoming festivals in Europe and my opening slot on the European leg of the Coldplay world tour,” said the Odd Future crooner. “Sorry as f**k, I’ll be back if you’ll have me.”

The announcement comes just days after Ocean abruptly walked off the stage at Norway’s Oye Festival after performing four songs. A festival representative told the crowd that he “suddenly got sick and lost his voice.”

Following the release of his critically-acclaimed album channel ORANGE in July, he toured briefly in the U.S. and was scheduled to open for Coldplay through September.
